Specification of Letters Patent.

Application filed Octber 25, 1915. Serial No. 57,789.

To all lwhom t may concern.'

Be it known that I, THOMAS H. RmnoU'r,y

ments in shelves and particularly to improvements in shelves adapted foruse in ovens.

One object of this invention 1s to so construct a shelf-that it may bereadily adjusted relative to itswidth and that at any width, within itslimits of adjustability, its load carrying member may easily be drawnout with its load whereby inspection of and access tosaid load arefacilitated.

Another object of the invention is to provide a shelf having a novelslidable load carrier or member.

Other objects of the invention willappear from the followingdescr'ption.

The invention consist in the novel construction of the adjustable loadcarrying member and its frame.

The invention also consists in such other novel features of constructionand combination of parts as shall vhereinafter be more fully describedand pointed out in the claims. v j

Figure 1, represents a front view of the improved shelf in position inan oven, the latter being indicated. Fig. 2, represents a plan view ofthe shelf. Fig. 3, represents a sectional view taken on line 3 3 Fig-2.

Similar characters of reference designate corresponding partsthroughout.

As shown in the drawings in its preferred form the improved shelfcomprises a main frame having the ways or tracksf, 5 bent at their rearends to furnish the overlapping arms 6, 6 which are slidably connected,for adjustment, by the guides 7, 7 Attached to the front ends of theways or tracks 5, 5 are the members 8, 8 having the bent ends 9, 9 andthe inwardly extending overlapping arms 10, 10 which latter are slidablyconnected by the guides 11, 11. At the rear portions of the ways ortracks 5, 5 are secured the members 12, 12 which correspond in somedegree to the members 8, 8 in that these members l2, l2 have theoutwardly bent ends 13, 13 and the feet 14, 14. These feet 14, 14 andthelguidesll, 11 support the main frame on the bottom of an oven O or onany plane surface as indicatedjat X in Fig. 3. The outwardly bentends'9, 94 and 13, 13 respectively of the members 8, 8 and 12, 12 affordextensions to which are secured the strips or bars 15, 15 adapted to bereceived by brackets B, B at the sides of the oven O or byany othersuitable sustaining devices. In order to prevent the tipping upward ofthe rear end of the main frame I prefer to provide one of the arms 6, 6with the clip or clamp 16 to adjustably secure the rod 17 which lattermay extend to the top of `the oven O as shown in Fig. 1.

The front members 8, 8 of the main frame are provided with the rotatablesheaves 18, 18 which sustain the riding side bars 19, 19 of the `shelfwhich side bars have the inwardly bent and overlapping arms 20, 20slidably connected by the guides 21, 21, these rear portions of the sidebars 19, 19 havingl the frames 22, 22 each furnished with a pair ofrotatable sheaves 23, 24, between which the ways or tracks 5, 5 of themainframe are engaged.

The front ends of the shelf side bars 19, 19 are connected by-members25, 25 depending from said side bars and having the overlapping arms 26,26 slidably connected by.

bars 30.30 which clear the member 29 of the other of said pairs ofmembers.

From the above description and by reference to the drawings it will beseen that the main frame is adjustable laterally to various sizes, inview of the pairs of slidable arms 6, 6 and 10, 10 and that, in suchadjustment, as the shelf is engaged with the ways or tracks 5, 5 of saidmain frame by its sheaves 18, 18, 23, 23, and 24, 24, such adjustment ofthe main frame will e'ect the adjustment of the shelf; that is, the mainframe and the shelf are both constituted by pairs of comico plementalmembers, the respective pairs being engaged. Thus the main frame and theshelf are both constituted by pairs of complemental membersconnected forlateral adjustment While the individual members of the frame and shelfare so engaged by said track and sheaves that the lateral adjust; mentof the main frame eects corresponding adjustment of the ,shelf and viceversa.

ln use, the main frame sustains the shelf,

' Patent- 1. A shelf mechanism comprising a main frame and a shelf eachconstituted by pairs of slidably adjustable members, said shelf membershaving-means engaged with the frame whereby said shelf follows alladjusting movements of the frame.

2. A shelf mechanism comprlsing amain frame having a pair of Ways eachhavlng innaoeeo wardly extending oyerlapping arms, guides forslidablyconnecting said arms, a shelf having rigid rside members andpairs of i11- wardly extending overlapping arms, means for slidablyconnecting said latter arms, and means mounted on said rigid sidemembers to slidably receive the ways of said main frame whereby the waysof said frame and said shelf are positively connected and all lateraladjusting movements of either are transmitted to the other.

3. A shelf mechanism comprising a main frame, having pairs of ways, armsextending inward from said ways and slidably connected, grooved sheavesrotatably mounted relative to said ways, and a shelf constituted by apair of adjustably connected members each of which has a track receivedin the related grooved shea-ve of said main frame,`

and a pair of grooved sheaves mounted on members of said shelf toreceive the respective ways of said main frame whereby said main framemembers and shelf members are positively engaged by said sheaves andeach follows all adjusting movements of the other.
